Several other similar bottom-up models possess the flavonstrahlung signature,
for example the Third Family Hypercharge Model [1]} and its
variants [2]}, gauged muon minus tau lepton number [3]}
and several other gauged \(U(1)\)  family non-universal
models [4]}. In the future, it may be of interest to compute
the cross-sections for these models too in order to see how they compare.
